ESG Advisory

Sustainability reporting that withstands the scrutiny of an audit. We help you determine what matters, disclose it against the standards your stakeholders expect, and build the governance and controls to make those disclosures defensible.

Sustainability disclosure, held to the standard of financial reporting.

Sustainability disclosure has moved from a voluntary communications exercise to a regulated, assurable component of corporate reporting. The International Sustainability Standards Board's IFRS S1 and S2, the European Sustainability Reporting Standards under the CSRD, and the maturing expectations of investors and lenders have converged on a single principle: ESG information should be prepared with the same discipline, connectivity to the financial statements, and evidential support as the financial numbers themselves.

Finspera 21's ESG Advisory practice is built for that reality. We do not produce narrative for its own sake. We start from a defensible materiality assessment, map the disclosure obligations and voluntary frameworks that actually apply to your business, and work back to the data, systems, and controls needed to report reliably against them. Every engagement is led by a practitioner who understands both the reporting standards and the accounting discipline behind assurable numbers.

Whether you are preparing your first climate-related disclosure, transitioning a GRI-based report onto an ISSB or CSRD footing, or readying your ESG data for third-party assurance, we bring a structured, audit-ready methodology with the directness of a specialist who stays on the engagement.

Capabilities

What we do.

We work in defined phases so that scope, effort, and cost are clear from the outset. Each phase produces a tangible output you own, and you can pause or extend the engagement at any natural break.

01

Materiality & stakeholder mapping

Defining what to report, and to whom, on a basis you can defend to an auditor and a board.

02

Standards-aligned reporting

Disclosures prepared against the frameworks your regulators, investors, and lenders require.

03

Governance & controls over ESG data

The internal architecture that makes a sustainability disclosure reliable rather than aspirational.

04

Assurance readiness

Preparing your disclosures and evidence to move through limited or reasonable assurance.

Our Approach

How we work.

A disciplined, staged engagement model, from first question to defensible outcome.

PHASE 01

Scope & diagnose

We confirm the regulatory and voluntary frameworks that apply to you, review your existing reporting and data, and agree the reporting boundary and value chain in scope.

PHASE 02

Assess materiality

We run the materiality assessment, single or double, as your obligations demand, engaging the relevant stakeholders and documenting the methodology and conclusions for audit.

PHASE 03

Map the gap

We compare your current disclosures, data, and controls against the applicable standards, and produce a prioritised remediation roadmap with clear owners and sequencing.

PHASE 04

Build & disclose

We help you stand up the data and controls, draft the disclosures, and ensure they connect coherently to the financial statements and the wider annual report.

PHASE 05

Ready for assurance

We assemble the evidence, dry-run the disclosures against assurance criteria, close residual gaps, and support you through the assurance provider's review.

Questions

Frequently asked.

Where should we start with ESG reporting?
Start with a materiality assessment. It pinpoints the sustainability topics that matter most to your business and stakeholders, so effort and disclosure land where they count. From there we shape a reporting roadmap aligned to the frameworks that apply to you. The partner who scopes this work stays with it through delivery, so nothing is lost in handover.
Does the CSRD apply to us, and how should we prepare?
Scope and timelines under the CSRD have shifted, so the first step is confirming whether and when you report, including exposure through a parent group or EU operations. We then map your position against the ESRS, find the data and governance gaps, and build a practical plan to close them. The aim is a report you can stand behind, not a box-ticking exercise.
Which reporting framework should we use, GRI, ISSB or TCFD?
It depends on your audience and obligations. GRI suits broad stakeholder reporting, while the ISSB standards, IFRS S1 and S2, serve investors and now carry the former TCFD climate recommendations. Many organisations report against more than one. We help you choose a coherent approach and build each disclosure once, so a single dataset feeds several frameworks.
How do you handle greenhouse-gas and emissions data?
We help you measure Scope 1, 2 and 3 emissions using recognised methods, and set out the boundaries and assumptions behind each figure. Scope 3 is usually the hardest, so we focus on the categories that are material and defensible. Sound emissions data underpins credible targets and stands up to scrutiny from investors and assurers alike.
What does it take to be ready for sustainability assurance?
Assurance tests whether your disclosures are backed by evidence. We prepare you by tightening data trails, controls and documentation, so every figure can be traced from source to report. Because the specialist who scopes the work also delivers it, our findings are practical and discreet. The goal is disclosure that earns trust and creates value, not merely meets a requirement.
